From the Moselund tunic page: “The weave is a 2/1 twill. The fabric had been fulled.[…] The tunic is of a kind known in Iceland as ‘bladkjortel’. The slit made the garment comfortable in movement, and suitable for working or riding in. The sides could be gathered up into the belt for additional freedom of movement, and could also be used as ‘pockets’ to carry things in.”
